Nice approach to a platformer. Controls are a risky but interesting choice. I didn't know it was time-depending until I died, and seemed a bit unfair to be honest.

Does it have music/sound? Because I didn't hear anything, but the settings have a volume control all the way up.

Anyway, cool thing. It is working, it does look it has a lot of potential. Well done! 

Interesting prototype/introcuction. You can probably design some devious puzzles with this. The simple graphics do look really nice. I experienced a bit of a lag within the labyrinth, but that could just be at my end.
